Four fire tenders were rushed to the spot and the situation is "now under control", Krishna told media.
Staffers tried to help patients out of the building in Noida, a suburban town in Uttar Pradesh on the outskirts of the national capital.
Thick smoke could be seen billowing out of the building in Sector 12. People stood on ledges and on balconies as rescuers tried to reach them by smashing glass window panes.
